Consumed Host Memory = The amount of physical memory that has been allocated to the virtual machine by you the VM administrator plus the overhead that the ESXi hosts to use in order to run the VM.
The memory overhead can vary depending on the virtual machine configuration. The following configurations impact on the memory overhead size;
- Amount of RAM assigned to the VM
- x86 or x64
- Number of vCPU’s
- Virtual devices such as keyboards, mice, USB
Active Guest Memory = This is the amount of physical memory that is actually being used by the guest OS. This figure is not 100% accurate and is calculated by ESXi based on sample information.
